The little gun roared sharply, slid quickly back and forward again in its recoil cylinders, and the mechanism clicked smoothly as another shell was thrown into the breech. For a moment my vision was obscured by the thick white cloud of smoke. Peering intently, I saw the unearthly monster flying more slowly--sinking. In a moment it was out of sight behind the purple trees. "Did you hit it?" Sam cried anxiously. "I think so. But why all the fuss about that one? There are plenty more back in the jungle." "Oh, didn't you see? It was carrying something!" "Carrying something?" "Mel, one of those red tentacles was wrapped around a _man_!" He had brought the lumbering machine about in the direction of the place where we had last seen the monster. We went at a reckless pace. The machine rocked and banged, and we were shaken up unmercifully when we crossed a dry watercourse. Two or three of the trees went down before our undeviating and irresistible advance, filling the air with purple clouds of petals from the great bright flowers. Then I saw before us, thirty yards away, the great strange creature lying flat on the ground, with wings outspread. Beneath it, in the coils of one of the thick tentacles, I saw the gleam of a naked human body. The machine jerked to a halt and I threw open the manhole and sprang out on the deck. In a moment Sam was beside me. He had buckled on an automatic pistol of the latest design and the heaviest caliber. He handed me a duplicate weapon, with ammunition belt and holster, with the warning, "We've got to expect the unexpected, and must be quick on the draw!" I fastened on the gun, and led the way down the ladder to the ground. In a few seconds we stood by the dead monster. Seen at close range, it was an appalling thing, indeed. It was very strange, and even the dead body of it showed cruel strength. The green wings were like tough green leather stretched over a metal frame. The body was armored with thick, rough brown scales. The tough scarlet skin of the tentacular limbs was smooth and rubber-like. Already the weird flower at the forward end was withered and black. The ground about the thing was stained with a flood of green liquid from the terrible wound the shell had torn. I hurried around it. Only the shoulder and arm of the human prey were in sight. Yes, it was a human being, and the skin had the clear smoothness of youth. I bent closer and perceived, with an odd admixture of feelings that made my heart beat wildly and then pause until I reeled, that the skin had a soft greenish tan. I saw that the body, lying under the wing alone, had not been crushed by the fall of the monster. "We'll be able to tell what manner of mankind we have to deal with here," Sam said, though I scarcely heard him. "If our man was at all civilized, there ought to be ornaments, or remnants of clothing. I hardly expected human life here. But it may be a human science that is threatening our world!"
